To prevent the unauthorized use, alteration or falsification of protected content, a variety of cryptographic techniques can be used. Cryptographic techniques are particularly in the context of access and usage control. Digital signatures can ensure, for example, authenticity. The versions mentioned are also available as an upgrade from Windows XP, but each requires a new installation.
In the context of electronic payment systems, encryption methods (especially the Secure Electronic Transaction (SET) system) ensure secure transmission of sensitive billing information (such as credit card number) over the Internet as shown by a Cisco Configuration Manager.
Furthermore, symmetric authentication systems in the context of so-called challenge-response method to contribute to the identification and elimination (device revocation) of manipulated DRMS equipment and programs, thus making media against unauthorized use. The aim of the different watermarking techniques is to permanently combine certain information with a media product.
The network for GSM is called PLMN (Public Land Mobile Network). It is connected to the Public Switched Telephone Network (PSTN), but also directly to other mobile networks (UMTS, LTE) and those of other operators.
Communication between the mobile phone and the base station (Network Management System). The TDMA (multiple access time division or Time Division Multiple Access) and FDMA multiple access (frequency division or for FDMA Frequency Division Multiple Access) is used to allow more users to be connected without saturating the network.
Characteristics of the radio interface. GSM uses two frequency bands, one for the uplink (TX) and the other for the downlink (RX) which is part of the control channels, the signal is modulated according to the distance between the GSM antenna.
The 880-915 MHz band is used in Europe for the uplink, while the 925-960 MHz band is used for the downlink.
